SPECIFICATION 'forrnng part of Letters Patent No.7'780,446, dated January 1'7, 1905.

I Application filed June 2, 1904. Serial No. 210,875.

Be it known that I, JAMES H. RICHARDSON, a citizen of the United States, residing at Rockyford, in the county of Otero and State of Colorado, have invented certain. new and useful Improvements in Dumping-Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will Yenable others skilled inthe art to which it 'appertains to make and use-the same. i

This invention relates to dumping-vehicles, more particularly to gravity dumping-vehicles; and the objects of the invention are to improve the construction of such devices and v be carried or handled in the way of transit or delivery under any Conditions.

To the accomplishment of these objects and such others as may hereinafter appear theinvention consists of a dumping-vehicle embodying the novel features of construction, combinations of elements, and arrangement of parts having the general mode of operation'substantially as hereinafter described, and particu? larly pointed outin the appended claims, reference being had to the accompanying-drawings, forming a part hereof, in which the same reference characters designate like parts throughout the several views, and in which-- Figure l shows a side elevational view of the assembled parts as applied to a railway-car.

Y. For convenience of illustration the inventially the center thereof, and on which are securely fastened vat intervals, as by angleplates 3, a number of transverse girders C,

suitably stiffened by angle-irons or other convenient means C3 and having their outer ends bound together, preferably by longitudinallyarranged channel-beams G2, which also act as bumpers for the sections of the car when in dumping position. Secured to the transverse girders C and rising vertically therefrom between the movable parts of the car-body are standards L, preferably of I-beam section,

IOO

across of the top of which and running longitudinally of the car-body is secured an anglebar M, heel up, so that the legs thereof overlap the inner edges of the sections of the carbody, acting as a deflector to prevent material from falling therebetween. Itis of course understood that any arrangement of overlapping shelf would be suitable for this purpose; but an angle-iron section is peculiarly adaptable in this connection and is therefore preferably used.

At each end of the car, a convenient distance away from the dumping-receptacle, are arranged plates E, suitably stiiened and braced to the nearest standard L by a plate E. These plates E form a supporting means for the operating and locking mechanisms to be hereinafter described. Outside of the plates E and over the I-beams C are built suitable platforms 4, having depending steps 5, as is usual in ear construction.

The transverse girders C are formed with a curved surface, (see Fig. 2,) on which, on each side of the center line, are secured a set of gear-teeth C4 in such manner that any one thereof may be removed and replaced independently of the others. To accomplish this end, the teeth are formed separately, being divided in the center of their roots, as at 6, Fig. 8, and tapered bearings 7 are drilled or otherwise formed in said root with such dividing-lineas a center. Through these bearings and through concentric holes drilled in the stiffening-flange C3 on the girders C are passed taper-headed bolts 8, drawn home by nuts 9. On each end of the set of teeth C4 is a terminating member C5, Fig. 2, having formed therein a substantially semicircular groove or recess, used for a purpose to be hereinafter described.

The ear-body or carrying part is formed in two longitudinally arranged parts or sections A, having substantially vertical inner sides and outwardly-flaring outer sides, forming hopper-like receptacles with partially rounded bottoms. At points on these rounded bottoms coincident with the girders C and gearteeth C4, formed thereon, are secured sets of gear-teeth B, constructed to intermesh with teeth C4. On each side of the teeth B are bolted `or otherwise suitably secured to the car-body strips D, which act as guides to keep teeth B in alinement with teeth C4. Teeth B are made independently removable for the purpose of replacement when worn out or for other reasons, and to this end are divided centrally of their roots, as at 6', and a groove 10 is also formed centrally over said dividingline, and in said groove, through holes 11, concentric therewith in the guides D, is passed a bolt orv other suitable securing means 12, fastened with a nut 13, the bolt being of such size as to be readily accommodated by the groove without impeding the proper working of the teeth. On each end of the set of teeth B is a terminating member B', Fig. 2, Vformed with a substantially semieircular lug or projection thereon and adapted to engage with the recesses CT. When the parts A are dumped, they fall to a position wherein the lower sides are at an angle of about forty degrees, as shown by the position A', Fig. 2.

The means for locking the part A ofthe car-body in upright position consist of two independent sets of locks, oneA set on the ends of the car-body and a second set between the sections A, constructed to lock the sides together. The latter will be described lirst.

It is seen by reference to Figs. 4 to 44 and Fig. 6 that the sections A are divided at intervals substantially opposite the girders C and standards L by partitions S into separate compartments. These partitions are so shaped as to -leave a projecting lug or shoulder S toward the lower portion thereof, Figs. 4 and 42, which projects into the space between the sections A. On the plate E is fastened a bracket K, and journaled between said bracket and a brace 14 between the beams (y is a shaft N, carrying an operating-handle N, here shown as a wheel, and a sl'irocket-wheel O, which is connected to another sprocketwheel O by a chain 15, Fig. 4. Sprocket O' is secured to a vertically-arranged shaft l. the ends of which are journaled in a plate 16 between the beams C' and a lug R, bolted or otherwise suitably secured to the standard L. Threaded on the shaft P is a block Q, adapted to bear against the shoulders S' of the partitions S, and thus act as a side lock to hold the sections A in upright position, Fig. 4 to 44. It is readily seen that block Q is easily released from engagement with the shoulders S' by turning hand-wheel N in the proper direction. Any suitable arrangement, as the usual ratchet and pawl, locks the shaft N from rotating. (Not shown.)

The locking means located on the ends of the sections (shown in Figs. 10, 10', and 10i) consist of a suitable bolt or bar V, having a bell-crank locking-lever V pivotally connected to one endand alug V2 formed on the other. This bar is adapted to slide through a housing 17 and in its extended position rests upon a lug 18, suitably secured to the car-body A. In moving the bar outwardly from the housing into locking position the locking-lever is swung over the top of the lug 18 and then brought into position to be held by a sliding check 19, mounted within a housing 2O and provided with a spiral spring 21, adapted to force the check outwardly. The sections are thus held securely together by the lug V2 bearing on the projecting end of the housing 17 and the lever V bearing against the lug 18. To the rear end of the check 1 9 is attached a ring or other projection 22 to prevent the cheek from being forced entirely out. To' release this lock, the lever V is forced ,from engagement with the check 19 and swung lOO IIO

. or dumped independently of the other.

free of the lug 18.l The barV is then forced outwardly, as shown by dotted lines, Fig. 102, and from there shoved home within thel housing 17, where itis out'of harms way in rescating the sections A. e

The mechanism for bringing the sections A back into loading position after having been dumped. by tilting the sameoutwardly will now be described, together. with lthe means for locking such. mechanism in any desired angular position of the sections.

Itv will be noted that upon releasing the two locking mechanisms already described (first the end locks V, &c., then the side locks Q, &c.,) the sections A A will automatically fall by gravity, the two sets of gear-teeth described intermeshing and the guides D car` rying the sections on their proper path. The sections fall until stopped by the bumpers G2 and by the check-chains T, securedto the sections A'and I-beams C', which normally rest in boxes U, preferably formed by bracing across two of the stileners 3. y(See Fig. 6.)

In the upper part of the bracket K on each end of the car is mounted a gear-wheel F on the ends of a shaft F', extending longitudinally of the car between the sections A, lhaving bearings in the standards L andjournaled von the tops of end plates E or otherwise suitably located. Gear-wheels F are providedy with lugs F2, on which and the end of shaft Fl lits a crank F2, by means of which power is applied. Meshing with gear F are two other gears, G and G', mounted on shafts G2 and G2, preferably journaled in the bracket K. Mounted on shafts G2-andG2, preferably in the rear of gears G and G', are spools J and J Below these spools vare shafts H2 and H3, conveniently located, as by journaling the ends thereof in plate E and girder C, and mounted thereon are drums H and H. 'Io theinner lower corners 23 of sections A or any other convenient place are secured one end of cables or chains 24 and 24', which pass down and over drums H and H', respectively, then up, and the other ends are secured to spools J and J respectively, (see Fig. 2,) in such manner that when gear F is rotated clockwise said cables or chains willbe wound on said spools. Gears G and G are connected to spools J and J by any Well-known clutch mechanism, (not sh0wn,) whereby one of the said gears maybe slipped forward on its shaft out of engagement with gear F, and either section of the car-body may thus be brought into position The means for locking this reseating-gear is shown in Figs. 11, 11', and 112 and consists of a sprocket -chain WV, adapted to engage with gear F, having one end pivoted in a suitable lug or projection 25, mounted on bracket K, and its other end provided with a recess forming a tooth 26, which engages under a similarly-formed projectionformed in aflug or projection 27, also mounted on bracket K. A

latch 28 is also pivotally mounted in lug 27 and serves to wedge and lock the sprocketchain W `in position. f

The operation of the device is obvious. l*In back into position and reseated whenthey are locked.
